Divisions:

This series provide frameworks in many segment variations that can be used to show flows in two directions. The circle in the middle is the starting point and the flows go left and right from the center. This bidirectional flow can be used to show two paths, pros and cons, two sets of responsibilities, etc.

This series is with wings; hf041 is exactly the same but without wings. Refer to the tutorial for formatting techniques and the animation example.
